Human exposure to soil contaminants in subarctic Ontario, Canada.

ABSTRACT:

Background

Chemical contaminants in the Canadian subarctic present a health risk with exposures primarily occurring via the food consumption.

Objective

Characterization of soil contaminants is needed in northern Canada due to increased gardening and agricultural food security initiatives and the presence of known point sources of pollution.

Design

A field study was conducted in the western James Bay Region of Ontario, Canada, to examine the concentrations of polychlorinated biphenyls, dichlorodiphenyltrichloroethane and its metabolites (ΣDDT), other organochlorines, and metals/metalloids in potentially contaminated agriculture sites.

Methods

Exposure pathways were assessed by comparing the estimated daily intake to acceptable daily intake values. Ninety soil sa
